Prestashop Module Form creation

I want to add 21 checkboxes and a text field(Name) in a good design way. Also there must be "check all button" to check all the checkboxes, how to do it in module PHP page in prestashop.
Since I am new to prestashop I don't know about the form submission, I have to save these two fields together as a json array in database.
Is that possible in prestashop? please help me regarding this.
prestashop version = 1.6
Thanks in advance
Sample code
protected function getConfigForm()
{
return array(
'form' => array(
'legend' => array(
'title' => $this->l( 'Generate Export Order Settings' ),
'icon' => 'icon-cogs'
),
'input' => array(
array(
'type' => 'checkbox',
'name' => 'display',
'values' => array(
'query' => array(
array(
'id' => 'all_fields',
'name' => $this->l('All Fields'),
'val' => '1'
),
),
'id' => 'id',
'name' => 'name'
)
),
),
'submit' => array(
'title' => $this->l( 'Save Export Settings' ),
'class' => 'button pull-right',
'name' => 'save-main-display-settings',
)
),
);
}
I don't know how to add check box in 3 columns and 7 rows and select all button to select all the checkbox.

You can use the following JS code to add check all functionality:
$('.chk_boxes').click(function(){
var chk = $(this).attr('checked')?true:false;
$('.chk_boxes1').attr('checked',chk);
});

In yii2 how to change Dropdown data as per role from?

I have data in Drop down list as per role(for every role table are different).
I don't have any idea how to do because I am not familiar with yii2 First select a role and after selecting role I want data from different different table as per role
<?= $form->field($model, 'role')->dropDownList( [ 'A' => 'Admin', 'M' => 'Member', 'P' => 'Practice', ],['prompt'=>'--Select a Role--',]);?>
<?= $form->field($model, 'code')->dropDownList(
ArrayHelper::map(Member::find()->all(), 'id', 'memberCode'),
['id'=>'memberCode']
);
?>

You Need to update your 2nd dropdown when you select any value from dropdown 1st. Lets say 2nd drop down have id #dropdown2 so, i dit in yii you can change it according to yii2.
echo $form->dropDownListGroup(
$model, 'id', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' => CSystemGenerated::getProjectName($model->c_id),
'htmlOptions' => array(
'prompt' => 'Select Project',
'ajax' => array(
'type' => 'POST',
'url' => your url,
'update' => '#dropdown2',
//'dataType' => 'json',
'data'=>array('id'=>'js:this.value'),
)
),
),
)
);
<?php
echo $form->dropDownListGroup(
$model, 'tag', array(
'wrapperHtmlOptions' => array(),
'widgetOptions' => array(
'data' =>$this->getTags(),
'htmlOptions' => array(
'prompt' => 'Select Tags',
),
)
)
);
?>

I'm trying to add custom tag to cakephp form input but it won't apply.
I am using Bootstrap switch
My code :
$this->Form->input('item_id', array(
'multiple' => 'checkbox',
'div' => false,
'data-label-text' => $items,
'class' => 'form-control',
));
att: i want to add item names as a 'data-label-text'
this is working (with out other attributes)
$this->Form->checkbox('aaa', array('data-label-text'=>'new item out'));
Any idea ? help ?

Try this
$options = array(0 => 'new item out 1', 1 => 'new item out 2');
echo $this->Form->input('item_id', array(
'multiple' => 'checkbox',
'div' => false,
'options' => $options,
'class' => 'form-control',
));

three selects each based on previous jquery

I'm trying to do 3 selects in cakePhp + jQuery first one with provinces, second - localities, third - schools in that place. Here is my cake code (so far):
echo $this->Form->input('proviences', array(
'type' => 'select',
'empty' => true,
'options' => $proviences,
'label' => 'Province',
'class' => 'proviences',
'before' => '<div style="float:left;width:180px"',
'after' => "</div>"
));
echo $this->Form->input('localities', array(
'type' => 'select',
'empty' => true,
'options' => $localities,
'label' => 'City',
'class' => 'localities',
'before' => '<div style="float:left;width:180px"',
'after' => "</div>"
));
$schoolList = array();
foreach($schools as $value) {
$schoolsList[]=$value['name'];
}
echo $this->Form->input('school_id', array(
'label' => 'Szkoła',
'options' => $schoolsList,
'empty' => true,
'before' => '<div style="float:left;width:240px"',
'after' => "</div>",
'onchange' => "submit();",
));
In $schools i have a list looking this way
array(
id1 => array(
'name' => 'some_name',
'province' => 'some_province',
'locality' => 'some_city'
)
)
and using this to get lists of provinces,localities and school names
I was trying to use this but couldn't get it working ;/
Filter three select boxes based on previous selections
Is there a way of doing it in jQuery without ajax?

you can do it without using ajax, but for that you would need the schools array on client side, and create/edit options based on that on the client side, too.
here is a working fiddle. (hastily thrown together, but you get the idea). You need to get the schools array into js, though. you could either use AJAX for that or, pass it as json on the page:
echo 'var schools = JSON.parse('.json_encode($schools).');
You have to think about where to place that, too, so that the variable doesn't leak into the global scope. you could put it in the jQuery closure, for example:
echo '(function($){';
echo 'var schools = JSON.parse('.json_encode($schools).');
// now the javascript from the fiddle...
echo '}(jQuery))';

Get value of selectbox with JsHelper in CakePHP

I have a select box, and I want to use it to Ajax-update some other content on the page. So I have bound an event handler using the JsHelper (jQuery) like so:
<?php
echo $this->Form->select('car', $cars);
$this->Js->get("#car");
$this->Js->event('change', $this->Js->request(array(
'controller' => 'cars',
'action' => 'view',
???,
array('async' => true, 'update' => '#car-view', 'evalScripts' => true),
true
));
?>
But how can I get the value of the select box to send as an argument to the cars controller (at "???" in the code above)?
I could do everything in javascript, but is there any way to do this in cake?

To be honest, I struggled with this a while back. I couldn't find anything that worked, so I ended up just going the straight javascript route.

I think you are looking for this:
$this->Js->get('#selectbboxid1')->event('change',
$this->Js->request(array(
'action' => 'function'), array(
/*'before' => 'showLoader();',
'success' => 'hideLoader();',*/
'update' => '#selectboxid2',
'dataExpression'=>TRUE,
'method'=>'POST',
'async'=>TRUE,
'data' => $js->serializeForm(array('isForm' => TRUE, 'inline' => TRUE)) )));
